CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This is a continuation-in-part of co-pending application Ser. No. 10 / 609,727, filed on Jun. 30, 2003, which is hereby incorporated by reference in its entirety.FIELD OF THE INVENTION
[0002] The present invention relates to a device for application to a barrier membrane.BACKGROUND OF THE INVENTION
[0003] Transdermal devices have been widely prescribed for decades in the treatment of is systemic diseases and local conditions. During passive transdermal delivery, an active agent is delivered into a mammal by using a concentration gradient across a barrier membrane (e.g., through passive diffusion through skin). For example, a patch containing the drug in high concentration is affixed to the skin of a patient.
[0004] Electricity may be employed to facilitate drug transport across the skin barrier. In electricity-assisted devices, an electric potential (voltage) is applied to the membrane to facilitate drug transport. In transdermal iontophoresis, a...
